SPECIFICATION forming part of Letters Patent No. 613,271, dated November1, 1898.

Application filed August 12, 1895. Serial No. 558,971. (No model.)

To all whom it may concern:

Be it known that I, CHARLES HENRY HEY- WOOD, a citizen of the UnitedStates of America, residing in Milwaukee, in the county of Milwaukee andState of Wisconsin, have invented newand useful Improvements inPrinting-Presses, of which the following is a specification, referencebeing had to the accompanying drawings and letters and numerals ofreference marked thereon.

This machine is designed to print, stamp, or emboss and apply governmentpostage or other stamps to envelops and cards. The paper, card, ormaterial may be fed in a continuous strip from a roll or be cut intosheets or blanks and fed as described in patent issued to me February 4,1890, or in any convenient or well-known way.

In the accompanying drawings, in which like letters and numerals ofreference indicate like parts, Figure 1 is a front elevation of myimproved construction, partly in section, with certain parts broken awayto disclose the mechanism. Fig. 2 is a vertical section of the machine,taken on line 00 a: of Fig. 1, looking from the right-hand side of themachine. Fig. 3 is a View of one of the form-roller-carriage gears andjournal made in one piece, on which is also fastened the gear 31. Fig. 4is a side elevation of Fig. 3. Fig. 5 is also a View of one of theform-roller-carriage gears similar to the one shown in Fig. 3. Fig. 6 isa side elevation of the gear shown in Fig. 5. Fig. 7 is a View partly insection of the ink-cylinders, distributing-rolls, form-rolls, and someadjacent parts, taken as seen from the righthand side of the machine inFig. 1, and represents the parts in the position reached at the time theimpression is being made. Fig. Sis a horizontal section taken throughthe printing-bed and frames in Fig. 1 from left to right. Fig. 9 is anelevation of the inkcylinders and distributing-rolls, and Fig. 10 is adiagram showing the centers of the different gears.

A general description of the construction of the machine is as follows.

In Fig. 1, A A represent the sides of the machine, (shown also in Fig.2,) B the girth or truss extending from one frame to the other, holdingthem rigidlyin position, and 0 an arch extending over and connecting:the top portions of the frames A A and providing a place on whichisfastened the tympan D or platen by which the impression is made. E isa spurgear on the crank-shaft G.

In Fig. 2, H is the driving-shaft, on which is fastened gear F. (Shownonly in this view.) The power is applied to this shaft, but it has beenomitted in the drawings, as the power may be applied in any well-known.manner, either by a friction-clutch or a tight or loose pulley.Crank-shaft G is made with two ofiset crank-motions 7, from which theprinting-bed receives its motion. On the right-hand end of thecrank-shaft is the bevel-gear I, transmitting motion through its mate Jto vertical shaft L. Vertical shaft L is supported in bearings K and M,fastened to the side of frame A. In this shaft L is securely fastened afeather 9, and sliding upon shaft L and feather 9 is the bevel-gear W.The feather 9 provides that gear W shall turn with the shaft L, while itis forced by hearing X to reciprocate upon the shaft, as willhereinafter be explained. In the frames A A are formed two channels orgrooves. In these grooves or channels are shown the vertical slides Qand R. Connecting these slides at their lower ends is the truss orI-beam S. This is rigidly fastened to the slides in question, havingears cast upon its under side, as shown in Fig. 1, through which arepins 5 5, on which are pivoted the connecting eye-rods 2 2, extendinginto the stirrups 1 1 and retained therein by nuts 3 and 4. At the upperend of these sides, extending from slide Q to slide R, is theprinting-bed frame t. This bed is formed of one piece, the centralportion of which is made to receive the type-chase. The ends are formedin journals on which rotate the form-roller-carriage frames. Thejournals of bed T are keyed into the frames Q and R by keys 47 and 48.

Meshing with the bevel-gear W on shaft L is a bevel-gear V, fastened tothe end of the horizontal shaft U. Just below gear V and fastened on theslide R is a box X, which surrounds the gear W, and as the slides R andQ, with box X, rise and fall through the action of the crank-shaft G thegear W is reciprocated upon the shaft L, while it is' revolved by thefeather 9. The motion thus received is transmitted through the bevelgearV to the shaft U, 011 which are the two gears Y and Z. These gears meshdirectly with the carriage-frame gears 17 and 18 on the printing-bedjournals T T.

Fig. 2 shows a shaft N, on which is lever 0, connecting through link Pto the center of the I-beam S. On the other end of the lever is fasteneda spring, the object of which is to counterbalance the moving portion ofthis machine.

A designates a plate connecting the tops of the side frames A A andbracing them against lateral strains.

For convenience in more readily understanding the machine I divide theremainder of the description into three mechanisms, as follows:printing-bed proper, form -rollers and cylinders, and ink-supply.

Printing-bed proper.1n Fig. 1, 40 is the chase fastened to the surfaceof the bed T. (Shown best, perhaps, in Fig. 2.) 50 is the type orelectrotype held in the chase.

26 26, Fig. 1, are tracks formed around the printing-bed T in suchmanner as to guide the form-rollers as they move around the bed, thetrucks upon the form-roller arbors rolling upon this surface, as shownin Fig.2. These tracks are of such shape that the form-rollers as theyrotate around the bed are carried into and out of contact with theink-cylinders at the proper time. Extending through this bed from end toend is the tie-rod 44. On this rod between the tracks 26 26 of the bed(best shown in Fig. 8) is sleeve 43. This sleeve extends and fitstightly between the two tracks 26 26. Tie-r0d 44 extends through theparts, as shown, all being bound tightly together by nuts 45 and 46.

In Fig. 2 will be seen the shaft 33 on the left side of the printing-bedcamway or track 26, and in Fig. 8 is shown a section through this shaftthat it may more clearly be understood. At each end of this shaft arepiniongears 32 and 34, the object being to transmit the motion from theoutside of the printingbed to the inside. This is done by the gear 31,fastened upon gear 17. (See Figs. 3 and 8.) The motion is thentransmitted to gear 35, fastened on the ink-cylinder frame 36 inside ofthe printing-bed.

Fowl-rollers and cyZmders.Figs. 3, 4, 5, and 6 are different views ofthe form-rollercarriage frames. In Fig. 3, 17 is a large gear twice thediameter of gears Z or Y on shaft U. The reason for this gear beingtwice the diameter will be apparent later. The gear is made with a largehub and with ears 19 and 19 projecting from the side. Through these earsare bored holes which serve to receive the eye-rods 20, as shown inFigs. and 6. Two of these eye-rods are used in each gear, only one beingshown in Figs. 5 and 6. At the upper end of eye-rods 20 is the rockingclaws 22, which in Fig. 1 are shown carrying the form-roll arbors 23 and3!). On this eyerod 20 is a spring 21, and through the rod is placed apin 27, thus causing the spring to retract the claws 22 toward thecenter of the gear-journals. In Fig. 2 it will be seen that there aretwo sets of form-rollers, one set 41 41 on arbors 23 and 38 being shownover the type, the other set 41 41 on arbors 38 and 40 being shown incont-act with the ink-cylinder 30. It will be seen that as gear 17 istwice the diameterof gear Z and as gear Z makes one revolution to everyimpression of the machine gear 17 could not rotate but half-way aroundat every impression. Thus if the form-rollers are in the position shownin Fig 2, where the crank 7 on shaft G is in its downward position, thenwhen the crank 7 is turned half-way around and the printing-bed has beenraised up and is making an impression the form-rollers would then be inthe position shown in Fig. 7, and at the next half-revolution of themachine, or when the crank again reached the position shown in Fig. 2,the form-rollers shown at the top of the printing-bed would have changedplaces with those on the ink-cylinders.

The construction of the form rollers is best shown in Fig. .1, in which23 and 39 are steel arbors extending through claws 22 22, having theroller composition 41 cast upon their centers and carrying wheels 24 24,held in position by nuts 25 25. As these formrollers roll around theprinting-bed on tracks 26 26 the wheels roll off this track into contactwith disks fastened on the end of the ink-cylinder arbors,which arenumbered 28 28 28 28 and are best seen in Fig. 1 of the drawings. Thesedisks 28 rotate in such manner that they come into the path of theroller-wheels 24 at a certain portion of their revolution. Eachcylinderhasdisksatitsextremeends. Thedisks are the same diameter as thecylinders, and as each set of the form-rollers pass around the bed theyovertake one of the cylinders to take ink, the operation being such thatthe cylinders as a whole make one revolution to the form-rollers as awhole making one revolution. Cylinder 30is arranged to supply ink toform-rollers 41 41 on arbors 23 and 38,\vhile cylinder 29 supplies 41 41on arbors 23 38. At every revolution of the machine a set ofform-rollers will overtake its supply-cylinder at the lowest positionshown in Fig. 2. The location of the centers of the form-roller-carriagegears and the centers of the ink-cylinder frames not being in line, butbeing arranged one below the other, as shown in Fig. 10, the sweep ofthe form rollers moving around the printing-bed being greater than thatof the ink-cylinders, consequently the form-rollers move faster than thecylinders. After the form -rollers leave this position they roll off thecylinder. At the time the machine is making an impression theformrollers are horizontally in line with each other, the cylindersbeing parallel, but the center of the movement of each is wide apart. Itwill be seen, therefore, that in order for the form-rollers to havereached the positions shown in Fig. 7 away from the cylinders each setmust gain or lose upon its own cylinder as they come to or move from theposition shown in Fig. 2. Thus during the operation of the machinetheset of form-rollers 41 41 on arbors 39 and 40 take their inksupplyfrom cylinder 30, as shown in Fig. 2, and then pass on and rollove-r'the face of the type, thereby inking the same, while at the sametime the alternating set of rollers will be taking ink from cylinder 29preparatory to inking the type in their turn.

Sleeve 43 in Fig. 8 has formed at one enda gear 43', also shown in Fig.9. As this sleeve 43 is rigidly held in the printing-bed, gear 43 isfixed and cannot revolve. Revolving on this sleeve 43 are placed twoframes 36 and 37. These frames are tied together and rigidly connectedby rods 42 and 58. On frame 36 is fastened a gear 35, and through thisgear rod 42 extends, firmly fastening it to frame 36. Frame 37 isslightly different from frame 36, inasmuch as it carries in addition twogears 64 64, fastened on the frame to mesh with fixed gear 43. On thearbors of the cylinders 29 and 30 are also fastened gears 65 65, alsomeshing with gears 64 64. Now it will be seen that if these two frames36 and 37 are revolved on shaft 43 and if gear 43 is fixed the gears 6464 will rotate around gear 43 and revolve the cylinders 29 and 30. Atthe extreme ends of the cylinder-arbors are fastened the disks 28 28 2828, described under head of printing-bed proper.

I have purposely shown how the motion is transmitted from gear 31 onjournalT through the gears 32 34 to the inside of the printingbed inorder to drive the gear 35 and frames carrying the ink-cylinders.

In Fig. 9 I have shown the cylinders 29 and 30 and distributing-rolls 56and 57. These rolls are made from roller composition. 55 is the metaldistributing-roll, (shown best in Fig. 8,) mounted on a fixed arbor 59,which extends from frame 36 to frame 37. Roller-compositiondistributing-rolls 56 and 57 are cast upon arbors 60 and 61, said arborsbeing carried in stocks 62 62, made adjustable in frames 36 and 37 andheld in posit-ion by adjusting-screws 63. 63. A further description ofthis method of holding, &c. is not required, as they can be held in anywell-known manner. It is simply necessary that the distributing-rollsshould make contact between the cylinders 29 and 30 and the metaldistributing-roll 55.

As the cylinders 29 and 30 rotate around the fixed gear 43 in thedirection indicated by the large arrow in Fig: 9 they are given a rotarymotion through the medium of the gears 64 and 65 in the direction of thearrow marked on eachcylinder. As their peripheries come in contact withthe composition rolls 56 and 57 these rolls will receive motion in thedirection as the arrows indicate and in their turn contact with thedistributing-roll 55 on the arbor 59. The means illustrated to obtainthe lateral motion of this distributing- I have shown no gearing forgiving this distributin g-roll a positive motion, although this issometimes necessary and is used on my machine, as such mechanism toproduce such motion is well known to those familiar with this branch ofmanufacture. Y

The distributing-roll 55 is the first roll to receive ink from theink-supply, and in Fig. 7 distributing-roll 55 is shown in the act ofreceivingthe ink from roll 14. The ink, being received by 55 at everyother revolution of the machine, is carried to the distributingrolls 56and 57 and then in turn given to the cylinders 29 and 30, any surplus onone cylinder being equalized by the action ofv these rolls before it-istaken on the form-rollers.

In7c-supply.0n shaft U in Fig. 1 are fastened two arms 10 and 11.Extending through bearings on these arms is the roll 13, carrying at itsextreme end a small wheel 16 andv just inside of this wheel a gear 15.The roll 13 is made of metal, and running in contact with said roll isthe composition roll 14, cast upon arbor 51 and also having bearings inthe arms 10 and 11. Fastened on I-beam S is a standard 12, extendingupward and terminating in a sleeve through which. shaft U passes, and onthis sleeve is out a gear 67. (Shown plainly in Fig. 7.) Beside the gearin Fig. 1 on sleeve 12 is shown a cam-slot 68, set obliquely and inwhich the wheel 16 travels. The function of the gear 67 is such that asit is fixed while the shaft U rotates and carriesthe arms 10 and 11 withrolls 13 and 14 the gear 15 on roll 13 will be caused to rotate as itrolls around the gear 12. The rotary motion thus imparted to roll 13,which is in contact with the composition roller .14, causes roller 14also to rotate in the direction indicated by the arrow shown in Fig. 7.As the shaft U carries the roll 14 around it will at each revolution bebrought into contact with the ink-fountain roll 53 in fountain 52, whichis fastened on the I-beam S. At each revolution as the roller 14 touchesthe fountain-roller 53 it will take therefrom as much ink as the scraper69 allows to escape, and owing to the continued motion and contactbetween rollers 13 and 14 the ink will be distributed on the two. As therollers 13 and 14 are carried around with the shaft U the roll 13 .willbe moved laterally upon the surface of roll 14 by the action of wheel 16following the cam-slot 68 and distributing the ink. At every otherrevolution of the machineas the roller 14 is brought over the cen ter ofthe shaft U it comes into contact with and then recedes from thedistributing-roller 55, the reason for this occurring at only everyother revolution of the machine being that the roller 14 is carriedaround the shaft U once every revolution of the machine, while thedistributing-roller 55 is carried around its central sleeve 13 onceevery two revolutions of the machine. As 14 and 55 come into contact inkis received from roller 14 and distributed and transmitted to theink-cylinders 29 and 30.

I have shown the roller 14 delivering the ink to the distributing-roller55; butI do not limit myself to just this arrangement, as by adjustingthe machine I can deliver ink to the rolls of each set of theform-rollers at every revolution of the machine, although thearrangement shown is clearly sufficient to supply the cylinders with allthe ink that is needed. If more is required, the latter adjustment orits equivalent can be made.

It will be seen that my printing-bed is made to reciprocate and allparts connected thereto are moved with it; but I do not confine myselfto the reciprocating bed, as it could be arranged to oscillate equallyas well.

I wish it understood that I do not claim anything shown in patents forbed and platen presses, No. 168,635, dated October 11, 1875; No.255,704, dated March 28, 1882, and No. 260,792, dated July 11, 1888, asthese inventions are based upon fixed printing-beds with moving platens.

Having therefore described my invention, what I claim, and desire tosecure by Letters Patent, is

1. In a printing-machine, a vertically-reciprocating frame, aprinting-bed carried by the frame and formed with fixed journals at eachend, revolving frames journaled on the fixed journals of theprinting-bed, one or more ink-cylinders and distributing-rollersjournaled in the printing-bed, and form rollq ers in the arms of theroller-carriage frame arranged to contact with the ink-cylinders and becarried over the printing-bed in their revolution.
